simple means for releasably securing the cover in a closed position.

A further feature of the invention is to provide a simple, inexpensive portfolio for the packaging and storing of flat articles, and which may contain printed indicia and colored decorations to add to the attractiveness thereof.

Other novel features of the invention will appear as the following specification is read in conjunction with the accompanying drawing, in

which:

Figure l is a perspective view of the in closed locked position.

Figure 2 is a perspective view of the portfolio in open position.

Figure 3 is an enlarged horizontal sectional view on the line 3-3 of Figure 1.

Figure 4 is an enlarged vertical sectional view on the line 4-4 of Figure 1.

Figure 5 is a plan view of the inner side of the portfolio is constructed.

Referring to the drawing by reference characters, the numeral 19 designates a portfolio constructed in accordance with the invention, and as illustrated in Figure 5, it will be seen that it is constructed from a single blank A of stiff foldable material such as cardboard. The blank A is scored on the spaced vertical fold scores 11 and 12, and also on spaced horizontal fold scores 13-13. The scores 1 I, 12, and 13 are triple scores to provide depth to the folds when the blank is folded on said fold scores to set up position for use. The fold scoring is performed from the outer surface of the blank. The scores 11, 12, and 13-13 define a rectangular shaped rear wall panel I l. Integrally connected to the top and bottom of the panel 14 along the scores 13-13 are substantially L.-shaped front wall forming flaps 15-15, the foot portions 16 of which extend the full width of the panel 14. The outer end of the leg portion 11 of each L-shaped flap 15 is slit inwardly from its side edge as at 18 for a distance approximating one-half of its width to provide a locking tab 19. The tab 19 is of a length portfolio less than the length of the slit and is formed with an outer rounded edge by cutting away a portion of the material. The tabs 19-19 extend in reverse directions to enable them to be brought into confronting interlocking engagement when they are folded inwardly in a manner to be presently explained to provide a front wall.

Integrally connected to the panel 14 along the score 12 is a full length side flap 20 of a width less than that of the leg portions 11-11 of the L-shaped flaps 15-15. The mid-portion of the flap 211 is slit on the spaced horizontal parallel lines 21-21 outwardly from the score 12, and also is slit vertically on the line 22, the slits 21-21 being connected to the ends of the slit 22 by arcuate slits 23-23. The aforesaid slits 21-21, 22, and 23-23 cooperate to provide a continuous line of out to facilitate the striking out of a looking flap 24 from the side flap 21]. The flap 24 is provided with rounded locking tabs 25-25 which may be flexed or folded on the scores 25-26 which are co-extensive with the slits 21-21. The looking flap 24 thus formed is in continuation of the panel 14.

Integrally connected to the panel 14 along the score 11 is a front cover panel 21 which is of rectangular shape and of a size approximating that of the rear wall panel 14. The cover panel 21 is provided with two spaced horizontal slits 28-28 which are located adjacent the free side edge thereof to respectively receive the locking tabs 25-25 when the blank is folded to set up position with the cover panel 21 closed.

To set up the blank A to form the portfolio 10, the end flaps 15-15 are folded inwardly on the fold scores 13-13 to a position substantially parallel to the rear wall panel 14. whereupon the locking tab ends thereof assume an overlapping relation, and by a slight flexing of the same, the slit portions 18-18 may be interfitted to effect an interlocking of the tabs 19-19 asbest illustrated in Figures 2 and 4. The locked flaps 15-15 provide a front wall disposed in spaced parallel relation to the rear wall panel 14. Next, the side flap 211 is folded inwardly on the score 12 over the locked flaps 11-11 during which operation the locking flap pops out from the body of the flap 20, and this fold formed by the score 12 together with the folds on the lines 13-13, flaps 11-11, and rear wall panel 14 cooperate to provide a pocket P into which sheets of writing paper, envelopes, and other flat articles may be inserted for packaging and orderly storing. After the insertion of fiat articles into the pocket P, the front cover panel 21 is folded inwardly to effect a complete closing of the pocket P and to overlie the flap 20. To lock the cover 27, the lockin flap 24 is folded upwardly on the score l2 and inwardly to lie over the outer side of the cover, after which the reversely extending tabs 25-25 are flexed on the scores 26-26 and inserted through the respective slits 28-28, at which time the cover 21 is locked against accidental opening. To obtain access to the contents of the pocket P, th operator pulls outwardly on the free side edge of the flap 24, whereupon the tabs will freely slide out of the slits 28-28 and the cover may noW be swung open in the manner of the cover of a book. The L-shaped flaps l'l-I1 when locked together provides a relatively large opening as best seen in Figure 2 to enable access to the pocket and to display portions of the contents thereof.

In practice, the outer sides of the blank A may contain printed matter appropriate to the articles to be packed into the portfolio, and colored decorations may be printed thereon to impart a more realistic portfolio appearance. Whereas the portfolio in will be found useful in the packaging of Writing paper and mailing envelopes, the same may be used for the merchandising of other fiat articles.

While I have shown and described what I consider to be the preferred embodiment of my invention, I wish it to be understood that such changes in construction, design, and material, as

- ing means on the flaps to secure come within the scope of the appended claims may be resorted to if desired.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A portfolio comprising a single blank of cardboard which is cut and scored to provide a rectangular rear panel, top and bottom flaps joined to the rear panel at the top and bottom respectively along hinged scores and capable of being partly overlapped when folded inwardly over said rear panel parallel thereto, interlockthem disposed over the rear panel as aforesaid, a relatively narrow side flap joined to the rear panel at one side along a hinge score so as to be folded inwardly over said top and bottom flaps when the latter ar interlocked, to provide a pocket, a front cover of a size and shape corresponding to the rear wall and joined to the rear panel at its other side along a hinge score So as to be folded over all of said flaps when the latter are infolded as aforesaid, to close said pocket, and interlocking means on the rear panel and the cover for securing the cover in the closed position,

2. A portfolio as set forth in claim 1, wherein the last-mentioned interlocking means includes a member in continuation of the rear panel and said member having oppositely directed locking tabs.
